to get access to a particular node for interactive use, use qsub, e.g.,
to get one GPU and one CPU core on node 7 for 1 hour for interactive use:
qsub -I -l nodes=nano7:ppn=1:gpus=1,walltime=3600
to get entire node 1 for 1 hour for exclusive interactive use:
qsub -I -l nodes=nano1:ppn=12,walltime=3600
better yet, do not allocate nodes for interactive use, instead just submit batch jobs, see for example Job Scripts section at https://kb.iu.edu/d/avmy for details. This is a much better way to share computing resources.
interactive jobs are limited to 12 hours maximum walltime per job.
batch jobs are limited to 96 hours
submit request to staff for longer batch jobs (up to 240 hours)
to see what’s running on the cluster, just run qstat
this is a shared resource, please keep in mind that other users are using it as well; do not take over the system beyond what you really need.
home directory is cross-mounted, but there is very limited storage size
run 'df -h /home' to see how much space is available
